This multidisciplinary project is a continuation of the geological survey of the James Ross Basin, that for more than 15 years is been performed for some of the involved scientists. The project plans to increase the knowledge of an important region of the Antarctic Peninsula, in particular its geological, environmental and climatic history. The project include the geological survey of the ... outcroping rock of the proposed areas, Cape Lachman on James Ross Island and Cape Lamb on Vega Island. On the sedimentary cretacic rocks the team will search vertebrates fossils, in particular dinosaurs and the associated flora and fauna. In order to increase the knowledge of the Antarctic climatic evolution and the Antarctic ice sheet during Cenozoic times, the outcroping cenozoic fossiliferous deposits will be studies. Lake core sediment will be obtained to perform paleoclimatic studies and paleosecular variations and/or reversion of the earth magnetic field. For environmental magnetism studies, ground samples will be collected to determine and compare some of the magnetic features in order to characterize the places affected by antropogenic polution like Marambio Base and those without pollution.
